Nchịkọta nke Njirimara Inductance| DỊKWA MMA

Na sekit, a na-emepụta oghere electromagnetic mgbe nke ugbu a na-agafe na onye nduzi. ịdị ukwuu nke oghere electromagnetic kewara site na nke ugbu a bụ inductance .

Inductance bụ ọnụọgụ anụ ahụ nke na-atụ ike nke eriri igwe iji mepụta induction electromagnetic. Ọ bụrụ na a na-etinye ọkụ eletrik na eriri igwe, a ga-emepụta oghere magnetik gburugburu eriri igwe, na eriri igwe ga-enwe flux magnet na-agafe na ya. Ka ike na-ebuwanye ibu n'ime eriri igwe, ka oghere magnetik na-esiwanye ike ma na-abawanye ụba ike magnet na-agafe na eriri igwe. Nnwale na-egosi na mgbagharị magnetik site na eriri igwe dabara na nke ugbu a na-abata, na a na-akpọ oke ha inductance nke onwe, nke a makwaara dị ka inductance.

Nkewa inductance

Nkewa dị ka ụdị inductor si dị: inductor ofu, mgbanwe inductor.

Nkewa dị ka njirimara nke iduzi ndọta: oghere oghere, eriri igwe ferrite, eriri isi igwe, eriri ọla kọpa.

Nkewa site na okike arụ ọrụ: eriri eriri antenna, eriri igwe oscillation, eriri akpaka, eriri igwe notch, igwe ngbanwe.

Nkewa site na winding windo: otu eriri oyi akwa, eriri igwe, eriri mmanụ a honeyụ.

Nkewa site na ugboro ọrụ: eriri igwe dị elu, eriri igwe dị ala.

Nkewa dị ka njirimara nhazi: magnetik core coil, variable inductance coil, code inductor coil, coil na-abụghị isi na ndị ọzọ.

Inductor oghere, magnetik core inductor na ọla kọpa isi inductor bụ n'ozuzu ọkara ugboro ma ọ bụ elu ugboro inductor, ebe ígwè core inductor na-akasị obere oge inductor.

Ihe na teknụzụ nke inductor

Inductor na-abụkarị nke skeleton, winding, ọta, nkwakọ ngwaahịa, ihe ndọta na ihe ndị ọzọ.

1) Skeleton: n'ozuzu na-ezo aka na nkwado maka ikuku ikuku. A na-ejikarị plastik, Bakelite na ceramics eme ya, nke a pụrụ ime ka ọ bụrụ ụdị dị iche iche dịka mkpa dị n'ezie. Obere inductors anaghị eji skeleton eme ihe, mana na-efegharị waya enamelled gburugburu isi ya. The oghere inductor adịghị eji magnetik isi, skeleton na ọta cover, ma mbụ ọnya na ebu wee wepụ ebu, na sere a ụfọdụ anya n'etiti coils.

2) Winding: otu coils nwere ọrụ a kapịrị ọnụ, nke nwere ike kewaa n'ime otu oyi akwa na multi-layer. Otu oyi akwa nwere ụdị abụọ nke ikuku nso na ikuku na-apụtaghị ìhè, na multi-layer nwere ọtụtụ ụdị ụzọ, dị ka oyi akwa oyi akwa, winding na-enweghị atụ, ikuku mmanụ aṅụ na ihe ndị ọzọ.

3) Magnetic isi: n'ozuzu na-eji nickel-zinc ferrite ma ọ bụ manganese-zinc ferrite na ihe ndị ọzọ, ọ nwere "M" udi, kọlụm udi, okpu udi, "E" udi, tank udi na na.

Ígwè isi: tumadi silicon ígwè mpempe akwụkwọ, permalloy na na, ya udi bụ ukwuu n'ime "E" ụdị.

Ihe mkpuchi mkpuchi: eji egbochi oghere magnetik nke ụfọdụ inductor na-emepụta ka ọ ghara imetụta ọrụ nkịtị nke sekit na ihe ndị ọzọ. Onye inductor nwere mkpuchi mkpuchi ga-abawanye mfu nke eriri igwe ma belata uru Q.

Ihe nkwakọ ngwaahịa: mgbe ụfọdụ ndị inductor (dị ka inductor koodu agba, inductor mgbanaka agba, wdg) merụrụ ahụ, a na-eji ihe nkwakọba mechie eriri igwe na isi. A na-eji plastik ma ọ bụ epoxy resin mee ihe nkwakọ ngwaahịa.

Ihe dị n'elu bụ nkọwa nke njirimara nke inductor, ọ bụrụ na ịchọrọ ịmatakwu banyere inductor, biko nweere onwe gị ịkpọtụrụ anyị.
